I have to control input from 1 to 9999999999 (that represents the registration number of school)
The primitive type long can only hold up to about 2.000.000.000, how can i store numbers of this size?
According to this, the
longdata type can hold values from -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807, using 64 bits. It should be able to hold 9,999,999,999. Are you sure that you are treating that value as alongin all places?
